What is a stock for kids? Nova has a tasty answer: imagine a giant pizza that stands for a whole company. Each slice is a share. If you own a slice, you own a small piece of the company. This lesson builds from that idea to stock exchanges, dividends and diversification.
A stock, also called a share, is a unit of ownership in a company. Companies sell shares to raise money to grow. People who buy them become shareholders. If the company does well, its shares may become more valuable; however, if it struggles, they may lose value.
